5.3.3 Parallel connection "Double Power"

In this way the system has only One output for the Load and One output for the battery.

a) Use separate input fuses for each CBI.

b) Make sure that the two CBI have the same settings: Battery type, Charging level current, Time

buffering, Life test...

c) Automatic configuration, Master-Slave. The devices decide themselves their Master and Slave

assignment randomly. The assignment is done at every power on, or after the connection of the cable

RJ45. Master device provide all the visual signals, the Slave device maintain the diagnosis LED always

ON.

d) Use the alarm contacts of both the two devices and deliver them at will.

e) For Start Battery there are two way, without mains voltage:

- push start button on both units

- connect Cable "RTCONN" on position 5, to connect pushbutton on a front panel.

5.3.4 Series connection:

voltage (e.g. from a decelerating motor or battery) which is applied to the output terminals.

5.4 OUTPUT LOAD (MAINS INPUT ON)

The output Load in normal mode, Mains Input Vac Voltage present, follow the charging battery dc output

voltage. The minimum and maximum range stabilized are the following:

CBI 12xx:11 – 14,4 Vdc; 15,5 Vdc for NiCd (Without battery connected out. Voltage fixed at 12Vdc)

CBI 24xx:22 – 28.8 Vdc; 30 Vdc for NiCd (Without battery connected out. Voltage fixed at 24Vdc)

CBI 48xx:44 – 57.6 Vdc; 62 Vdc for NiCd (Without battery connected out. Voltage fixed at 48Vdc)

Thanks to the All In One units, it will be possible to manage the power. The available power, is

automatically allocated between load and battery: supplying power to the load is the first priority of the

unit; thus it is not necessary to double the power and also the power available for the battery will go to the

load if the load requires it.

In "Power Boost Mode" the maximum current on the load output is the 2 times the rated current 2 x In

(Iload = In+ Ibatt) in continuous operation and 3 times the rated current 3 x In (Iload = 2In+ Ibatt) for 4

seconds; after this parameter the devices is electrically protected against overload and short circuit.

• In "Power Boost Mode", if the the battery provide current to the load for a time more than 4 minutes,

the device give message (8 Blink), this consequently means that the battery is discharging. If the

Mains Input Voltage fall below a Threshold level (50% of the Typ. Vac input) the battery is

immediately connected to the Output Load, without any interruption.

• Voltage dips: In this situation the voltage in the output load it is the same of the battery.

• To Avoid deep battery discharge, the battery will supply the load until battery voltage reaches 1.5

V/cell. Below this level the device automatically switches off to prevent Deep discharge and battery

damage.

Power supply can be paralleled to increase the output

power, devices can be paralleled for 1+1=2 to obtain

the double power of a single unit. The possibility to

put in parallel connection it is only in SIZE 3 devices

the

"P"

CBI2420AP, CBI4810AP), to attain the sum of the

current at the same output voltage. It is necessary to

use

standard

UTP

ERJ.CBI.004 for RJ45, and connect by Aux2 of each

device. The communication protocol is based on

CAN2.0A standard.

It is possible to connect as many units in series as

needed, provided the sum of the output voltage

does not exceed 150Vdc. b) Voltages with a

potential above 60Vdc are not SELV anymore and

can be dangerous. Such voltages must be installed

with a protection against touching. c) For serial

operation use power supplies of the same type. d)

Earthing of the output is required when the sum of

the output voltage is above 60Vdc. e) Keep an

installation clearance of 10 mm (left/right) between

two power supplies and avoid installing the power

supplies on top of each other. Note: Avoid return
